ＭＶＭ属自主性细小病毒，对相当多种类的体内外生长的肿瘤细胞和转化细胞有抑制作用。本文对ＮＢＫ细胞的软琼脂克隆形成率和染色体进行了分析，确认ＮＢＫ细胞为转化细胞，且对ＭＶＭ敏感。在此基础上，比较了两种细小病毒ＭＶＭ宿主细胞ＮＢＫ和Ａ＿９的细胞存活率、单位体积培养液中的细胞产量和病毒产量，认为Ａ＿９细胞更适合于作为细小病毒ＭＶＭ的宿主细胞进行病毒的制备和生产。 MVM is an autonomous parvovirus that inhibits a wide variety of tumor cells and transformed cells grown in vitro and in vivo. In this paper, the soft agar clone formation rate and chromosomes of NBK cells were analyzed to confirm that NBK cells were transformed cells and sensitive to MVM. On this basis, cell viability, cell yield per unit volume, and virus yield of the two parvoviral MVM host cells NBK and A_9 were compared. It is considered that A_9 cells are more suitable for the virus-hosting of parvovirus MVM host cells. Preparation and production.
